This invention relates to wireless communication systems, specifically managing local area data network (LA PDN) connections in mobile networks. The problem addressed is ensuring efficient and timely release of local area data network connections when a terminal moves outside the service area or when a predefined timer expires after establishing a packet data unit (PDU) session for the LA PDN. The method involves monitoring the terminal's location and the status of the PDU session. If the terminal moves out of the service area for the LA PDN, the system initiates a release procedure for the PDU session. Additionally, if a predefined timer expires after the PDU session for the LA PDN is established, the system also triggers the release procedure. The PDU session establishment procedure involves setting up a connection between the terminal and the LA PDN, allowing data exchange. The release procedure terminates this connection, freeing up network resources and ensuring proper management of LA PDN connections. This approach optimizes network resource usage and maintains efficient connectivity for mobile terminals.

16. The terminal of claim 15, wherein the PDU session establishment procedure is not performed, in case that the current location of the terminal is not in the at least one service area for the LA PDN.
This invention relates to wireless communication systems, specifically to a terminal device configured to manage packet data unit (PDU) session establishment procedures based on its geographic location. The problem addressed is the unnecessary establishment of PDU sessions when the terminal is outside designated service areas, which can lead to inefficient resource usage and unnecessary signaling overhead in the network. The terminal includes a processor and a memory storing instructions that, when executed, cause the terminal to determine its current location and compare it against at least one predefined service area for a local area packet data network (LA PDN). If the terminal's location is outside all defined service areas for the LA PDN, the terminal suppresses the initiation of a PDU session establishment procedure. This prevents the terminal from attempting to connect to the LA PDN when no service is available, reducing unnecessary signaling and conserving network and device resources. The terminal may also store configuration data specifying the service areas for the LA PDN, which can be updated dynamically. The invention ensures that PDU sessions are only established when the terminal is within a valid service area, optimizing network efficiency and user experience.
17. The terminal of claim 15, wherein in case that the terminal moves out of the at least one service area for the LA PDN after the PDU session for the LA PDN is established using the PDU session establishment procedure, a release procedure for the PDU session for the LA PDN is performed.
This invention relates to wireless communication systems, specifically managing local area data network (LA PDN) connections in mobile terminals. The problem addressed is ensuring efficient and reliable handling of PDU (Protocol Data Unit) sessions when a terminal moves outside the service area of an LA PDN after the session has been established. The terminal includes a communication module configured to establish a PDU session for an LA PDN using a PDU session establishment procedure. The LA PDN provides localized data services within a specific geographic area. If the terminal moves outside this service area after the session is established, the communication module initiates a release procedure for the PDU session. This ensures that resources are properly deallocated and the terminal does not attempt to maintain an invalid connection, improving network efficiency and reducing unnecessary signaling. The release procedure may involve notifying the network of the session termination, releasing allocated resources, and updating the terminal's connection state. This mechanism prevents service disruptions and optimizes network performance by avoiding unnecessary session maintenance for an LA PDN that is no longer accessible. The invention applies to mobile devices operating in environments where localized data services are provided, such as enterprise networks, campus networks, or public Wi-Fi zones with specific service areas.
18. The terminal of claim 15, wherein in case that terminal moves out of the at least one service area for the LA PDN and a predefined timer is expired after the PDU session for the LA PDN is established using the PDU session establishment procedure, a release procedure for the PDU session for the LA PDN is performed.
This invention relates to wireless communication systems, specifically managing local area data network (LA PDN) connections in mobile terminals. The problem addressed is ensuring efficient and timely release of local area data network connections when a terminal moves outside the service area or when a predefined timer expires after the connection is established. The invention describes a method for handling a protocol data unit (PDU) session for a local area data network (LA PDN) in a wireless communication system. The terminal establishes a PDU session for the LA PDN using a PDU session establishment procedure. If the terminal moves out of the service area for the LA PDN and a predefined timer expires after the PDU session is established, a release procedure for the PDU session is automatically performed. This ensures that resources are not unnecessarily occupied when the terminal is no longer within the service area or when the session has been active for too long. The invention improves network efficiency by preventing unnecessary resource allocation and maintaining optimal network performance. The solution is particularly useful in scenarios where terminals frequently move in and out of local area networks, such as in smart city environments or enterprise networks.
